Abstract The association between plants and flower visitors has been historically proposed as a main factor driving the evolutionary change of both flower and pollinator phenotypes. The considerable diversity in floral morphology within the tribe Antirrhineae has been traditionally related to pollinator types.

Opuntia is the most diverse and widespread genus in the cactus family. In spite of the strong relationship with biotic pollination, little is known about their floral nectaries. We present the first deep structural and ultrastructural description of the floral nectaries of two Opuntia species (Opuntia anacantha var. retrorsa; Opuntia elata var. elata),

Variation Among Floral Visitors in Pollination Ability: A Precondition for Mutualism Specialization
Science, 1984The unusual floral biology of a neotropical herb provided an opportunity to determine that floral visitors varied significantly in their ability to effect fruit-set. Pollination efficiency and visitation frequency varied among Hymenoptera (five taxa), which were responsible for 99 percent of all fruits set.

Beetles as floral visitors in the Magnoliaceae: an evolutionary perspective
Arthropod-Plant Interactions, 2021Due to its ancient origin in the Permian and the high proportion of beetle-pollinated taxa within ancestral magnoliid lineages, it has been hypothesized that beetles were among the first floral visitors of the proto-angiosperms on Earth. Thus, beetle-pollinated flowers have become important model systems essential for the study of the origin and ...

Animal pollination is responsible for the majority of the human food supply. Understanding pollination dynamics in agricultural systems is thus essential to help maintain this ecosystem service in the face of human disturbances. Surprisingly, our understanding of plant–pollinator interactions in widely distributed smallholder agricultural systems is ...

AbstractPremiseAnimal pollination is critical to plant reproduction and may cause convergent evolution of pollination syndromes. Pollination syndromes in Castilleja have been distinguished based on floral traits and historical observations of floral visitors. Here we addressed these questions: (1) Can pollination syndromes be distinguished using floral
